This was the behaviour which was there before JDK-8249548 for JRadioButton and I am just reverting to it. As explained in the PR description, the behaviour before JDK-8249548 was as below

Before fix for JDK-8249548
JToggleButton:
    For all L&Fs, user can not navigate/select the buttons added to ButtonGroup properly as mentioned in the JDK-8249548.
JRadioButton:
    For Synth L&F (Nimbus L&F), user can not navigate/select the buttons added to ButtonGroup.
    For AquaL&F, user can select the buttons added to ButtonGroup by pressing left/right key and needs to press the "space" to perform the set Action.
    For Other L&Fs, user can select/navigate the buttons and the set Action is also performed without pressing "space"
